▎ 摘  要

NOVELTY - Method for treating graphene containing acidic wastewater involves filtering graphene containing acidic wastewater, treating filtrate through reverse osmosis membrane module to obtain concentrate (C1) and permeate (P1), adjusting pH of permeate (P1) to 6-7 using alkaline solution, again treating the permeate (P1) through reverse osmosis membrane module to obtain concentrate (C2) and permeate (P2), and continuously deacidifying the permeate (P2). USE - The method is useful for treating graphene containing acidic wastewater (claimed). ADVANTAGE - The method is simple and convenient to perform, and reduces sulfuric acid concentration to less than or equal to 10 mg/l.
